# #  本demo测试时运行的环境为：Windows + Python3.7
# #  本demo测试成功运行时所安装的第三方库及其版本如下：
# #   cffi==1.12.3
# #   gevent==1.4.0
# #   greenlet==0.4.15
# #   pycparser==2.19
# #   six==1.12.0
# #   websocket==0.2.1
# #   websocket-client==0.56.0
# #   合成小语种需要传输小语种文本、使用小语种发音人vcn、tte=unicode以及修改文本编码方式
# #  错误码链接：https://www.xfyun.cn/document/error-code （code返回错误码时必看）
